Hello Aspirant,
Hope you are doing well.

Because it encompasses all parts of electrical engineering and has extensive experience in the manufacture and maintenance of instruments, instrumentation seems to have a wider application span. Construction, heavy metals and mining are among the many industries with good potential for growth.

Polymer engineering, on the other hand, focuses on chemical compounds and their aesthetics, as well as all of their associated byproducts. Polymer engineering The scope of the project is restricted to chemical processing and pharmaceutical firms.
Hope you got the answer to your question. Incase of any queries, feel free to question. Have a great day!
